Fuel oil atomization method for pulverized coal burner and atomization device

The invention discloses a fuel oil atomization method for a pulverized coal burner and an atomization device. According to the fuel oil atomization method for the pulverized coal burner, diesel oil is carried out by means of the negative pressure, relative to a diesel oil channel, formed by compressed air at the pressure of 0.45 MPa at an inlet of a mixing chamber, the oil operation pressure which is originally 2.0-2.5 MPa is decreased to about 0.35 MPa, and the pressure of the compressed air is controlled to be 0.45 MPa, so that a mixture is sprayed out in an atomized state after the oil and air are sufficiently mixed, combustion is sufficient, air pollution is avoided, flame adjustment can be conducted conveniently according to requirements after the pressure is decreased, the flame stability is high, and scouring to a refractory lining is greatly reduced. According to the atomization device, a one-way oil pipe is changed into an oil-air mixed spraying pipe, and the atomization device is composed of an atom
